BAG CLOSURE Filed Nov. 30, 1928 El n vent-oz M abs-1. M Earm Patented Jan. 6, 1931 UNITED STATES MAIBEL MGCARTY, F. rnrw', INDIANA BAG CLOSURE Application filed November 30, 192s'.* s iia1no. 322,923. r

The present invention is directed to improvements in bag closures. V The primary object of the invention is to provide a device of this character designed 6 particularly for closing the discharge mouth of a dust collecting bag used in connection with vacuum sweepers, the construction being such that the bag can be readily opened to remove the contents thereof.

Another object of the invention is to provide a device of this character so constructed that the mouth of the bag will be held firmly closed, the construction being such that no sharp corners or projections are in evidence, thereby preventing the likelihood of catching draperies or garments thereon.

Another object of the invention is to provide a device of this character which is exceedingly simple in construction, efi'icient in operation, durable, and one which can be manufactured at a very small cost.

With these and other objects in'view, this invention resides in the novel features of construction, formation, combination and fully described, claimed, and illustrated in the accompanying drawing, in which Figure 1 is a side elevation of the bag, showing it in relative position thereof with respect to the sweeper handle. 'Figure 2 is a longitudinal sectional view through the bag closure.

Figure 3 is a transverse sectional view therethrough. 7

Referring to the drawing, 1 designates, a conventional formof sweeper having the nozzle 2 towhich is detachably connected the dust collecting bag 3, said bag being formed of suitable fabric, as customary. The closure comprises a bar 4:, said bar having a longitudinal groove 5 formed therein and in which is pivotally connected one endof a rod 6, said rod being threaded, as at 7, the purpose of whichwill be later explained.

The bar 4: is provided upon one end with an integrally connected head 8, while cooperating with. the other end is an adjustable head 9, said head having a threaded bore 10 formed therein for engaging thethreaded end arrangement of parts to be hereinafter more "further description, and it will be understood of therod 6, the purpose of which will'appear later. i

The bar 4 is provided with an eye 11 and to whichis connected'the snap hook 12, said hook having a chains'ectionlii carried thereby; Engaged with the chain section is an eye 14: adapted to be screwed into the handle 15-of the sweeper in order to hold the closure or member 4 in proper position with respect to the-handle.

It Will be obvious that when the mouth or discharge end of the bag is engaged in the groove 5 the rod 6 will hold the folds thereof tightly closed, and at which time the head is rotated upon the threaded end of the rod in order that it will firmly engage the bar 4. to hold the rod 6 from accidentally disengaging the groove.

Obviously when it is desired to remove the closure it is only necessary to rotate the head 9 in a direction to disengage the end of the bar, whereupon the rod can be swung downwardly, as indicated in dotted lines in Figure 2 to permit ready removal of the bag to empty the contents therefrom when desired.

It will be observed that the heads 8 and 9 are of such formation that no sharp corners or edges are present which will prevent the same from catching or tearing the clothing of the user.

From the foregoing, it is thought that the construction, operation and many advantages of thefherein described invention will be apparent to those skilled in the art, without that various changes in the size, shape, and proportion and minor details of construction maybe resorted to without departing from the spirit or sacrificing any of the advantages of the invention. 99

What is claimed is: a o i 1. A bag closure of the class described comprising a bar, arod having one end pivotally connected to the bar, a head adjustably mounted upon the rod, said head being adapted to enga e the bar to hold the rod engaged with the ag, as and for the purpose set forth.

A bag closure of the class described comprising a bar having alongitudinal groove formed therein, a rod having one end pivotally connected to the bar and movable in the groove, a head threaded upon the free end of the rod for engagement with the bar to hold the rod within the groove, and in engagement with the bag. v

3. A bag holder of the class described comprising a bar having a head fixed upon one end, said bar having a longitudinal groove formed therein, a rod, means for pivotally connecting the rod to the bar, said rod having a threaded end, a head engaged upon the threaded end and rotatable to engage or dis engage the adjacent end of the bar, said rod, 1 serving to hold the mouth of the'bag closed when the mouth of the bag is engaged in the groove. 7 I V 4. A bag closure comprising a bar, said bar having a longitudinal groove formed therein, a rod having one end pivotally connected to the bar, a head adjustably mounted upon the free end of the rod, said head being adapted, when moved one direction to eng e thebar to hold the rod in the groove.

n testimony whereof I aflix my signature.
